For anyone else (considering) switching file manager: Check if it depends on the gvfs package or not. You either want it (virtual filesystem support, stuff working "out of the box", background daemon, DE integrations) or you don't.
So there's one factor to cut the search-space in ~half :)
I'm recently trying out worker[0] and so far it's great.
